Abstract

The composition comprises an aqueous solution of H2SO4, a nitro- substituted aromatic compound, and optionally a fluoride ion producing species, and a surfactant. The composition can selectively remove hard surface layers deposited through flame, plasma spray, and detonation gun techniques on superalloy substrates by contacting the above stripping solution in a heated bath wherein the bath is continuously agitated by an ultrasonic agitation means.
